It's certainly not PC to blame the victim, but in cases like this they ultimately hold the bulk of the responsibility for what occurred.
I'm a scientist and have worked in labs where chemicals like this are used. You ABSOLUTELY KNOW that this stuff is crazy dangerous... there's simply no way you don't. Even as an undergrad your profs and older students tell you stories about how dangerous this stuff is.
If you don't have a chemistry background then I know it's hard to put the incident in question into perspective... but let me put it like this: It would basically be like a nuclear scientist working in a radiation lab who just reached in with their bare hands and picked up some highly reactive radioactive substance, walked around with it and then died of radiation poisoning (then everyone trying to blame the 'lab' afterworlds).
The university/lab certainly has some questions to answer (such as why was someone who was clearly inexperienced and not qualified to be performing such experiments given a key to the building and allowed to access such dangerous chemicals on their own?), but again if you're a chemist you know this stuff is crazy dangerous and if she didn't feel comfortable handling it she should have sought additional assistance and supervision... which given the lack of protective clothing it and standard safety precautions it was obvious she didn't know what she was doing.
I do feel really bad for this girl and her family/friends as nobody wants to see something like this happen... but people need to stop trying to find a scapegoat here and accept that there's a strong element of personal responsibility at play here.
No amount of safety procedures and training will matter if an inexperienced student with a key to the lab decides to come in on their own and mess around with crazy dangerous chemicals... period.
